The Presumptuous Philosopher doesn't think that in every particular clash the bigger hypothesis wins, because there are many possible ways for the universe to be big. The Presumptuous Philosopher just says the universe eventually turns out to be big. Big Bang won over Steady State, but in an open universe (which I believe this is) the Big Bang universe is "infinite" anyway. Now, infinity is a special case, and I suspect that the configuration space may be finite; but that's a separate story - the point is, the universe still turned out to be very big, just not in the particular Steady State way.
